JACOB FRUEH, OF CHICAGO, ILLINOIS.

SIPHON.

To all whom it may concern:

Be it known that I, JACOB FRUEH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Siphons; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specication, and to the figures and letters of reference marked thereon.

This invention relates to siphons such as are designed particularly for drawing liquids from casks or barrels into bottles or other small receptacles, and the objects of the invention are to provide a simple,.convenient apparatus with which the iiow of liquid may be started without the use of the users mouth and lungs, and with which the flow of liquid may not only be controlled, but stopped at will, or automatically sto ped when the smaller vessel is sufliciently led and the liquid in either instance being retained in the siphon ready to again inaugurate a flow when desired.

Generally speaking, the invention embodies a Siphon having a pump in which the pump valves are automatically opened and held open after the iiow of liquid has been inaugurated by the operation of the pump, and in addition, when so desired, an automatic stop-valve controlled manually to arrest the flow of liquid at any time, or automatically by a float operated by the liquid in the vessel being filled, and also having means whereby the stop valve may be opened manually when the flow of liquid is to be again inaugurated.

Referring to the accompanying drawings: Figure l is a section in a vertical plane through the pump and liquid controlling mechanism of a siphon embodying the present improvements. Fig. 2 is a similar view taken in a vertical plane at right angles to the plane of Fig. l. Figs. 3 and 4 are detail views of the lever for manually controlling the stop valve. Fig. 5 is a transverse section on the line 5-5, of Fig. l, and Fig. 6 is a similar section on the line 6 6, of Fig. l.

Like letters of reference indicate the same parts in all the figures.

ter of the present invention is preferably located in proximity to or forms a part of the discharge end of a flexible siphon tube A, it being understood that said tubeA is passed through the bung hole or aperture in the top of a storage barrel or cask, and the discharge end of the siphon located at a point below the liquid level in the barrel or cask.

In the apparatus illustrated, a pump cylinder B is provided, and within the same is a piston C, mounted on the end of a tubular piston rod C. The upper end of the rod is in communication with and forms an eXtension of the flexible Siphon tube A. The piston is provided with a packing c, preferably adapted to be expanded by setting up its confining heads in the usual manner, and the liquid passing through the hollow piston rod discharges into the pump cylinder through side passages c', Fig. 1, communieating with a transverse passage c2 in a bridge piece c3 carrying a gravitating valve D for closing the outlet to the passage and checking the reverse flow of liquid or air through the passage and siphon tube. The valve stem cl of the valve D extends through the bottom of the piston and projects a sufficient distance to effect the elevation or opening of the valve when the piston is at the bottom of the cylinder, and consequently when in this position, a free opening is established for the iiow of liquid through the siphon tube and piston. Upward movement of the piston allows the valve to close and creates a vacuum below the piston, as in an ordinary pump. In the bottom head E of the cylinder is an upwardly closing check valve F, normally held to its seat by a spiral spring f, but having a central stem f with which the stem of the piston valve is adapted to contact when the piston is in its lowermost position, whereby both valves will be opened.

With the arrangement thus far described, the operator by grasping the cylinder in one hand and the piston rod in the other hand, and reciprocating the piston or the cylinder with relation to the piston a few times, may draw the liquid into and through the Siphon tube, then by pushing the piston to the bottom of the cylinder both valves will be opened, leaving a free passage for the continued flow or siphoning of the liquid. In the preferred arrangement, and in order to retainthe piston at the bottom of the cylinder, a yielding retainer is provided. The retainer shown is in the form of a spring catch Gr secured to the piston and projecting through an opening g in the upper p iston head. At its upper end is a shoulder or incline. g adapted to pass within the cylinder head to resist the upward movementJ of the piston, but the shoulder is of suchY form as to yield and permit the movement of the parts upon the application of a pressure greater than would be exerted by the liquid tending to elevate the piston. If so desired, however, the shoulder may be inclined suiiiciently to require the attendant to release thecatch before the piston can be operated.

VThe mechanism for stopping the iow of liquid through the Siphon is preferably located below the pump mechanism proper, and in the particular embodiment illustrated is contained within a cylindrical prolongation of the cylinder in the form of a detachable housing H. This housing H is provided with side passages it communicating at the upper ends with the lower end of the cylinder and at their lower ends opening into a central valve chamber L, the upper part' of the latter in turn communicating with other side passages h2 opening or communicating at their lower ends with the passage below the housing. A very light stop valve I is located in the valve chamber L, being guided by the removable head c' and a downwardly extending boss c. rIhe valve is adaptedV to close against its seat l by an upward movement in the direction of the flow of the liquid passing through the housing from the siphon tube and pump, whereby the movement of the liquid tends to close the valve. This stop valve is provided with a flexibly connected downwardlyv extending stem le carrying at its lower end a small float K, normally adapted, by reason of its weight, to hold the valve in its openY position, but should said float be lifted, as by the rising of the liquid level in vessel in which the ioat is placed, the stop valve will be lifted, closed, and by the pressure of the liquid itself kept in its closed position, even though the discharge end of the siphon be lifted out of the liquid receiver.

The float itself is conveniently located in a tubular prolongation L, having bottom and side discharge openings for the liquid, the means whereby the stop valve may be manually controlled being located above the tubular extension. This means for manually controlling the stop valve embodies a bifurcated arm M, projecting into an annular housing N, located between the housing H and the tubular extension L and in position to embrace the valve stem between the stops The arm M is adjustably mounted ona4 transverse shaft M, journaled in a Y projection a onthe housing N, and isl adapted to either elevate and close the said valve, to hold it in an intermediate position, or to depress and hold the valve open.

To operate the arm and valve manually,

Y the outer end of the shaft is provided with a spring or transversely yielding operating arm O, having a thumb-piece@ at the end against which the operators thumb or finger may be pressed. At a point in proximity to the end of the yielding Yarm there is located a retainer therefor embodying two recesses it and R', in which the arm will rest for supporting thel valve either in its closed or intermediate position, and a bottom shoulder R2 against which the armmay be pressed bottom stop R2, is an incline. R3', against` which the end of the arm rides and byV which,

owingV to the transverse resiliency of the arm, the latter will be moved baci; into. theV recess R, whenever released by the attendant, thus insuring the retention or support of the valve normally in its intermediate 1 liquid below the stop valve after the latterY has closed, a small air vent S isformedin the housing below the stop valve, preferably in the head of the housing, and in close proximity to the tubular extension, in order that any liquid which may find its way through said vent will travel down on the outside of the tubular extension into the re-V ceptacle being filled.

'ln the practical operation of the device,

the attendant grasp's the cylinder and hous-A ing in one hand, depresses the stop valve operating arm to its full extent, and gives the piston a suHicient number of reciprocations to start they flow of liquid. The piston is left in its lowermost position and the operating arm of the Vstop valve is 'permitted to return to its intermediate position; The How of liquid will continueuntil the ioat rises, or if itV be desired to interrupt'the iow at any time, the operating arm of the stop valve may be elevated to its upper notch, thereby closing the valve. yAssuming that the {ioat has operated to close the stop`V valve andl the attendant desires to shift the discharge end into another receptacle' or to lift the'same 'above the liquid level" inthe casl, the operating arm of the'stop, valvek is' moved to'theg upper notch so as to insure the holding of the valve closed, then in order to start the flow of liquid it is simply necessary to lower the discharge end and depress the operating arm so as to open the valve. When the operating arm is released the 'alve moves back to its normal intermediate position.

The main object in employing the retainer for holding the piston in its lowermost position, with the pump valves open, is to prevent the lifting of the piston under the pressure and impact of the liquid when the stop valve is suddenly closed, and hence in cevices having no stop, valve or automatic means for shutting oftl the flow of liquid the retainer for holding the piston in its lowermost position may be omitted.

Inasmuch as it is preferred to employ7 a stop valve which will, when closed, be held in its closed position by the pressure of the liquid, it may here be remarked that with this construction it is important that the valve should normally stand just a sufficient distance from its seat to prevent a normal flow of liquid from picking the same up and closing it until the valve is slightly lifted by the float, when the closing action should be quick and entirely automatic. It is for this reason that the operating arm for the stop valve is provided with a means for holding it in its intermediate position to form a support which will permit the valve to close automatically.

Having thus described the invention, what is claimed, is
